Precise Models for Power Loss Analysis in a 15-level Asymmetric Reduced Switch Inverter

In the examination of power converters, power losses are the most important metrics, and since they are approximated well enough, they have a considerable influence on both economic and technical evaluations. In comparison to high-switching frequency modulation, the purpose of this article is to demonstrate that switching and conduction losses, which are both types of power losses, are much lower in low-frequency switching modulation. Phase Disposition (PD), a pulse width modulation (PWM) method that is based on high-frequency multi-carriers, and Selective Harmonic Elimination Pulse Width Modulation (SHEPWM), which operates at a fundamental switching frequency, are the two switching modulation techniques that will be utilized in this investigation. The objective of this study is to evaluate the power losses that occur in an asymmetric multi-level energy converter that has fifteen levels of reduced switches. To determine the switching losses that occur in multi-level inverters, a MATLAB Simulink model has been constructed. The PLECS software was used to construct the thermal model of the recommended inverter, which would further facilitate in-depth research. A comparison of the switching losses and conduction losses of the proposed inverter system is carried out by this study via the use of the PLECS thermal model and MATLAB simulation.
